PUNCHING-TOOL FOR EMBROIDERY.

Specification of Letters Patent.

Patented Oct. 26, 1909.

Application filed May 1'7, 1909. Serial No. 496,393.

To all whom it may concern:

Be it known that I, MARSHALL N. JARVIS, a citizen of the United States, residing at Portland, Middlesex county, State of (Jonnecticut, have invented new and useful Improvements in Punching-Tools for Embroidery, of which the following is a specification.

This invention relates to a punching tool of novel construction for perforating a textile fabric as a step preliminary to embroidering the same.

The tool is of simple construction, is not liable to tear the fabric, and permits the size of the holes punched to be accurately gaged.

In the accompanying drawing: Figure l is a side view of my improved punching tool; Fig. 2 a longitudinal section thereof, and Fig. 3 an enlarged cross section on line 33, Fig. 1.

The handle 10 of the tool is provided with a tubular sleeve 11, which, if desired, may be made integral with the handle and has a beaded edge 12. The punch 13 is composed of a tapering front section and of a cylindrical heel 1% which is telescoped by sleeve 11. The latter is slotted longitudinally as at 15, and is provided with a scale 16 running along one of the edges of slot 15. Into slot 15 extends the threaded stem 17 of a set-screw 18, said stem being tapped into heel 14. Upon stem 17 is mounted a curved or saddle-shaped washer 19 that straddles sleeve 11 and projects over both edges of slot 15. A turn of screw 18, to the right, will cause the washer to be pressed against sleeve 11, and to thus lock punch 13 in position, while a turn of the screw to the left, will slacken the washer and release the punch. In addition to the function of frictionally holding the punch to the sleeve, the washer has the additional function of constituting, with its forward edge, an indicator moving along scale 16. By means of this indicator the distance to which the punch is projected out of the sleeve, to obtain the desired size of the hole, may be readily controlled.

It will be observed that an annular space or clearance 20 is formed between the beaded edge 12, of sleeve 11, and the side of punch 13. This clearance serves to protect the perimeter of the hole punched from contact with the end of sleeve 11, so that the latter, while constituting a stop that defines the play of the punch, will not in any way enter or disfigure the hole formed in the fabric.

I claim:

1. A punching tool for embroidery, comprising a handle, a slotted sleeve, a punch telescoped by the sleeve, a clamp-screw extending through the sleeve-slot and tapped into the punch, and a curved washer mounted on the clamp-screw and straddling the sleeve.

2. A punching tool for embroidery, comprising a handle, a slotted sleeve having a gage, a punch telescoped by the sleeve, a clamp-screw extending through the sleeveslot and tapped into the punch, and a curved washer mounted on the clamp-screw and straddling the sleeve, the forward edge of said washer constituting an indicator that cooperates with the gage.

Signed by me at Portland Connecticut this 13 day of May 1909.

MARSHALL N. JARVIS.
